Environmental pollution is the major problem in these days. Earth polluted day by day. If it continues, then no one can live in this world. Government and some private institutions taking some steps to overcome these issue. CO2 is the main cause for global warming. The earth heating level keep on increasing due to high emission of CO2. Government in UK has imposed new rule in taxation. Cars which emits zero CO2 will get the benefit of zero pollution. There are some cars in the market receiving these benefits. It is helpful for environment as well as for car manufacturers.
Public always want to buy a car which has zero annual tax. Due this tax method, car sales increased and pollution level minimized. It would be good if all countries in the world follow the same policy. Golf BlueMotion, Ford Fiesta 1.6 Econetic, Toyota Prius, BMW 320d EfficientDynamics are few who got this tax benefit from the government.
